Japan is quickly becoming a leader in the field of cybersecurity. Over the past few decades, the nation has implemented several processes to strengthen its focus on IT security and protect its citizens. Japan's initiatives involve educating the public on cyber risks, enforcing anti-cybercrime laws, and investing in cyber defense equipment and resources.

In terms of conferences and events, Japan is home to several important cybersecurity events and conferences. These include the “Japan Computer Security Conference”, which is held annually in Tokyo and is the largest IT security event in the country. Other conferences include the Japan Security Network Symposium, the IECS International Conference on Information Technology and Security, and the Japan Information Security & Lightweight Cryptography Conference.

Additionally, Japan hosts several national and international cyber competitions, such as the National Information Security Practice Championship and the Japan Network Security Contest. These events are designed to motivate and reward innovative ideas in the field of cybersecurity, often showcasing advanced technologies developed by experts from around the world working to improve cyber safety.

The country also has a long-standing commitment to international collaboration, with the Japan Cyber Security Initiative (JCSI) a cooperative effort between the government and industry to strengthen ties between organizations across the globe. The JCSI is supported by the National Institute of Information and Communications Technology (NICT) and provides a platform to share cybersecurity-related information and initiatives to make cyberspace more secure.

26th December 2025 | International Conference on Intelligent Autonomous Systems (ICoIAS) 2025

The 7th International Conference on Intelligent Autonomous Systems (ICoIAS) 2025 is a scholarly platform that gathers researchers, engineers, and educators worldwide to explore the latest advances and practical challenges in autonomous system technologies. Emphasizing innovations in intelligent control, robotics, multi-agent systems, and cyber-physical security, the conference fosters interdisciplinary collaboration to address complex problems such as actuator saturation, time-varying disturbances, and system dynamics coupling.

While the event broadly covers control theory, adaptive learning, and motion planning, it also highlights critical cybersecurity aspects related to cyber-physical systems and network security. Attendees gain insights into emerging intelligent methodologies that enhance autonomous systems' reliability and resilience, making this conference a key venue for those advancing autonomous technology with an eye on secure and fault-tolerant designs.

28th February 2026 | SECCON 14 Open Conference

SECCON is the largest CTF competition in Japan. We hold an in-person event called "Dennoh Kaigi" (電脳会議) alongside with SECCON CTF Final competition every year. Many workshops, presentations, and mini CTFs are gathered in Dennoh Kaigi. "Open Conference" is a presentations track of Dennoh Kaigi.

At last year's SECCON Open Conference 13, various presentations were made, including on attack methods against browser extensions, the development of attack detection technology for connected cars using machine learning, and experiences taking on OSINT CTF.
